一种基于电力载波通信的路灯控制系统集中器的设计

在基于电力载波通信技术的路灯控制系统中,集中器承担所有路灯的管控任务,对系统的可靠性工作起着至关重要的作用。设计了一款基于电力线载波技术的路灯集中器,实现三相路灯可靠管控。该集中器基于32位高速处理器和嵌入式操作系统,通过软、硬件的协同配合,实现控制系统通信协议管理、集中器与分别连接于三相的路灯终端通信以及集中器与远程管理中心信息交互。通过搭建测试平台对其控制功能及性能进行测试,测试结果表明,该集中器能够满足路灯控制系统中实时性、可靠性的要求。

Design of concentrator for road lamp control system based on power-line communication

In the road lamp control system based on the power-line communication technology, the concentrator is used to control the road lamps, which is very important to the system''s reliability. A new concentrator based on power-line communication technology is designed. A 32-bit high-speed processor and the embedded operating system are used in the concentrator. With the synergy of the software and the hardware, the communication protocol management, the communication between the concentrator and terminals of the three-phase road lamps, and the information interaction between the concentrator and the remote management center are obtained. The control functions and the performances of the concentrator are evaluated with the test platform, and the results show that the concentrator can meet the requirements of the real-time and the reliability of the road lamps control system.
